Embodiment Construction

[0044] A 3D video playback method and system provided by the present invention, in order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] A kind of 3D video playback method that the embodiment of the present invention provides, such as figure 1 As shown, it mainly includes the following steps:

[0046] Step S100: Classify the 3D video program according to the intensity of the motion elements in the screen content to obtain the motion intensity coefficient; and embed the motion intensity coefficient of the screen into the 3D video program data stream.

[0047] For example, the motion intensity coefficient value D of the picture can be evaluated by...

Abstract

The invention relates to the technical field of 3D videos, and discloses a 3D video play method and a 3D video play system. The method comprises the following steps of: grading 3D video programs according to the intensity of movement elements of picture contents in the 3D video programs to obtain movement intensity coefficients; and when the 3D video programs are played, extracting current movement intensity coefficients in real time, and controlling the opening and closing speed of shutter type 3D glasses and the play frame rates of video frames of the 3D video programs according to the extracted current movement intensity coefficients. Therefore, the method and the system can realize the control over the opening and closing speed of the shutter type 3D glasses and the play frame rates of the video frames of the 3D video programs according to the movement intensity coefficients of the 3D video programs, and by a play content-related adaptive shutter speed adjustment method, reduce problems on health caused by the long-term watching of the 3D videos, reduce shutter type 3D video watching discomfort and influence on the health of a user, provide convenience for the user and simultaneously prolong the service life of the shutter type 3D glasses.

Description

technical field [0001] The present invention relates to the technical field of 3D video, in particular to a method and system for playing 3D video. Background technique [0002] The shutter (SG) 3D imaging technology using time-sharing technology is widely used in the display of 3D TV and movies. The principle of the shutter-type (SG) 3D imaging method is to use the shutter-type 3D glasses to quickly close sequentially, so that the left and right eyes can see different TV images, and superimpose each other to produce a 3D effect. [0003] However, in the existing technology, when 3D video is played, due to the existence of the phenomenon of persistence of vision, when watching 3D TV programs, the human eye will feel "a certain distance from the position but overlapping pictures", which causes 3D "ghosting" and Factors that directly cause "dizziness". [0004] And when watching fast and intense sports pictures for a long time, the degree of dizziness and fatigue will be agg...
